Longitudinal prediction of DNA methylation to forecast epigenetic outcomes

no code implementations19 Dec 2023 Arthur Leroy, Ai Ling Teh, Frank Dondelinger, Mauricio A. Alvarez, Dennis Wang

Our model is trained on a birth cohort of children with methylation profiled at ages 0-4, and we demonstrated that the status of methylation sites for each child can be accurately predicted at ages 5-7.

Machine Learning for a Low-cost Air Pollution Network

no code implementations28 Nov 2019 Michael T. Smith, Joel Ssematimba, Mauricio A. Alvarez, Engineer Bainomugisha

Data collection in economically constrained countries often necessitates using approximate and biased measurements due to the low-cost of the sensors used.

Adversarial Vulnerability Bounds for Gaussian Process Classification

no code implementations19 Sep 2019 Michael Thomas Smith, Kathrin Grosse, Michael Backes, Mauricio A. Alvarez

To protect against this we devise an adversarial bound (AB) for a Gaussian process classifier, that holds for the entire input domain, bounding the potential for any future adversarial method to cause such misclassification.

Differentially Private Regression and Classification with Sparse Gaussian Processes

no code implementations19 Sep 2019 Michael Thomas Smith, Mauricio A. Alvarez, Neil D. Lawrence

We experiment with the use of inducing points to provide a sparse approximation and show that these can provide robust differential privacy in outlier areas and at higher dimensions.

Physically-Inspired Gaussian Process Models for Post-Transcriptional Regulation in Drosophila

1 code implementation29 Aug 2018 Andrés F. López-Lopera, Nicolas Durrande, Mauricio A. Alvarez

Since the post-transcriptional regulation of Drosophila depends on spatiotemporal interactions between mRNAs and gap proteins, proper physically-inspired stochastic models are required to study the link between both quantities.

Generalized Wishart processes for interpolation over diffusion tensor fields

no code implementations25 Jun 2016 Hernan Dario Vargas Cardona, Mauricio A. Alvarez, Alvaro A. Orozco

The aim of this work is to develop a methodology for DTI interpolation that enhance the spatial resolution of DTI fields.
